Exactly how conductive is perfect-surface rhodium? Apparently at least as good as gold but with a more balanced impedance curve, specifically better retrieval of higher frequencies - it’s definitely not warm by signature. Some have found silver to work better in their system than rhodium, but what I understood is that it’s not necessarily any less revealing, just neutral.
Since rhodium is acclaimed for its neutrality, why isn’t it used more often?
Would it be technically difficult to rhodium-plate copper cables? I’ve only seen it on terminations.
Please discuss this wonderful noble metal.
